The current methods of turfgrass evaluations are often based on human-based assessment methods. However, eliminating subjective errors from such evaluations is often impossible. This research compared the accuracy of human-based and digital image processing-based methods for quality assessment of turfgrasses. Four turfgrass plots were evaluated using the two mentioned methods. In the human-base...

This is an instructional document concerning the steps required to read and display the unprocessed sensor data stored in RAW photo formats. RAW photo files contain the raw sensor data from a digital camera; while it can be quite scientifically useful, raw data must generally be processed before it can be displayed. In this tutorial, the nature of the raw sensor data is explored. The scaling an...

We develop a method to create taxonomies in large social networks solely based on users group membership information. We illustrate our technique using an example of the Flickr photo sharing network. This photo sharing community is a social network that enables users to collectively store digital pictures, interact and form groups of interest. Based on our earlier research of success indicators...

Japanese lacquerware has been used from long ago in Japanese daily life. Makie is a famous surface decoration technique using metallic powders, color pigments, and lacquer. We propose a method for real-time rendering of Makie. The optical properties of the Makie surface is represented using Bidirectional Reflectance Distribution Function (BRDF). Sphere environment maps are generated for the rea...

In recent years the availability of GPS devices and the development in web technologies has produced a considerable growth in geographical applications available on the web. In particular the growing popularity of digital photography and photo sharing services has opened the way to a myriad of possible applications related to geotagged pictures. In this work we present an overview of the creati...

Serendipity is an engaging, deeply personal and even magical experience to some. While serendipity has been noted to arise during people’s interactions with digital photos, we have yet to understand how this occurs or how it could be supported during-and-through the use of technology. Inspired by findings about serendipity arising from people’s shuffle listening, we designed a digital photo dis...

Digital photo collections—personal, professional, or social— have been growing ever larger, leaving users overwhelmed. It is therefore increasingly important to provide effective browsing tools for photo collections. Learning from the resounding success of multi-dimensional analysis (MDA) in the business intelligence community for On-Line Analytical Processing (OLAP) applications, we propose a ...

In Flux, an application for digital photo collections, we provide methods for organizing and sharing photos in a convenient manner based on real-world physical interaction on a tabletop system. Additionally, the system supports four different orders based on quality, time, similarity and a combination of the latter two. The problem of scalability, which is especially relevant for a real-world s...

Photo collections are one of the promising sources to tell story of life in this digital era. In this paper we present our work on organizing photos of a lifetime by exploiting semantic annotations. The complexity in using semantic technology is managed by introducing an annotation template corresponding to who, when, where, and what. Semantics of each dimension are semiautomatically annotated ...
